🌟 Key Features of Suniso SL 32 (POE)
-
Lowest Viscosity Grade (ISO VG 32): This is a very light viscosity grade, crucial for high-speed, highly efficient compressors (like small rotary or scroll types) where minimal friction (low viscous drag) is required for peak energy efficiency.
-
100% Synthetic POE: A fully synthetic Polyol Ester oil, mandatory for use with HFC refrigerants (R-134a, R-410A) and suitable for HFO blends.
-
Rapid Oil Return: Its low viscosity ensures extremely fast and reliable oil return from the heat exchangers to the compressor. This is critical for preventing oil logging in compact systems and maintaining optimal heat transfer efficiency.
-
Superior Low-Temperature Fluidity: Features one of the lowest Pour Points (as low as -48^C) in the SL series. This makes it ideal for extremely cold applications and guarantees the oil remains fluid and non-congealing.
-
High Viscosity Index (VI): Has a very high VI (approx 125-130), indicating its viscosity is very stable and changes minimally across a wide range of operating temperatures.
-
High Thermal Stability: Maintains sufficient Thermal Stability (Flash Point 220^C) to resist decomposition, despite being a lighter oil.
